Commit Message

Use loglevel instead of console

The [`loglevel`][1] package is a drop-in replacement for `console`,
which lets us set the level of logging we wish to see.

This is particularly useful if we want to silence noisy logs (eg in
tests where we deliberately cause failures).

This change notably removes the `debug` flag from `Connection`.
Logging should be controlled through the provided interface (see below).

## Backend

The log level is controlled on the backend through the `Backend`
constructor. For example, to enable only errors:

```js
const Backend = require('sharedb');

const share = new Backend({
  logLevel: 'error',
});
```

## Client

The client-side log level can be set through a static method exposed on
the `Client`:

```js
const Client = require('sharedb/lib/client');

Client.setLogLevel('error');
```
